Hi everybody i had an account on the forum but i lost it so i just register with a new email.
I have a friend who had a jewelry store a guy went to sell a watch for his gold price. He show me and it was a vintage patek philippe calatrava. I don't know the model neither the date of production.
At the moment the watch is not working but i think it is just a little problem with the mainspring.
The watch is in 18 carat, do you thing it is worth to repair and resell and what price can he get of a working watch like this ?
i ll upload new photo when i can.
Thank you for your help.
